2. Forcing social media firms to delete specific kinds of content is another (albeit controversial) example.
3. Redacting all info about Saudi involvement in the 9-11 reports is a great example of censorship under the pretext of national security.
4. The SESTA/FOSTA bills are a recent (but again somewhat controversial) example.
5. Plenty of movies have been censored. One can easily google examples of this.
6. Many works of music too. Just ask the rappers.
7. Forbidding swear words in public/recorded speech is/was a great example. Although it is also an example of self-censorship among Americans.
All of your other examples involve private censorship (which can be rephrased as "people and companies exercising their property rights and freedom of association"), not government censorship.
Definitely an example of mandated censorship, corruption, and maybe some kind of conspiracy. Maybe protecting politicians' and Saudi's interests at everyone else's expense. Even if it kills a bunch of us. If that's how they use the power, they don't deserve to have it.
"4. The SESTA/FOSTA bills are a recent (but again somewhat controversial) example."
Where exactly is that private censorship?
